Wireless network cards allow our computers are connect to the internet remotely no need to use cables via WLAN. This type of card is the most practical and currently most used by modern electronic devices and laptops.
On the other hand, the kind of ethernet card, is the most common in desktop computers; this allows cconnect to internet services through cables. These are connected to the card by an Ethernet connector and allow the connection between different computers, although there are times when a computer does not recognize the Ethernet cable.
It is important to highlight that the network cards are what make it possible for us to interact in a simple and orderly way with the internet servers. Either via wireless or Ethernet.
